Details on this mission type
Full name Earth radiation budget from GEO
Definition This type of mission designates two measuring systems in geostationary or higher orbits : (i) broad-band radiometry of the total upward radiation (emission from the Earth's amosphere to Space and of short-wave reflected solar radiation); (ii) incoming solar radiation. In complement to the Earth Radiation Budget monitoring from LEO, measurements acquired from several GEO satellites around the globe enable capturing diurnal variations. The L1 Lagrange libration point is also a privileged vantage point for solar monitoring
Relevant instruments and their contribution

The sorting column describes how the instruments, by design, have the potential to contribute to certain pre-determined capabilities, assuming nominal operation of space and ground segments. For this particular capability, instrument performance is considered to be driven by:

  • Earth radiation budget from GEO or from L1;
  • Total and spectral solar irradiance from GEO or from L1.

 Sorting criteria and colour code:

  1. ERB measured in SW and total (SW+LW), with supporting narrow-bandwidth channels   Flown in the L1 Lagrange libration point.
  2. ERB measured in SW and total (SW+LW).  Flown in GEO.
  3. Total Solar Irradiance measured in the range from UV to FIR.  Flown in GEO.
  4. Spectral irradiance measured in the range from VIS to SWIR.  Flown in the L1 Lagrange libration point.
